GAS COOKING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 689,91 1, datedDecember 31, 1901.

Application filed December 29, 1900. Serial No. 41,528. (No model.)

To a/ZZ whom, it may concern:

Be it known that 1, EDMOND W. T. RICH- MOND, a subject of the Queen ofGreat Britain, residing at Summercourt,Romford,Essex county, England,have invented certain new and useful Improvements in Gas CookingAApparatus, of which the following is a speciiication.

This invention relates particularly to that part of a gas cookingapparatus known as the hot-plate;77 and the object of the invention isto improve the general construction of this part of the cooker and toprovide improved means for grilling and boiling and novel deviceswhereby certain parts of the apparatus may be reversed-z'. e.,transferred from one side of the cooker to the other.

In the accompanying drawings, Figure lis a top plan view of my improvedhot-plate, with the bars which support the cooking utensils removed.Fig. 2 is a detail top plan view of a portion of the hot-plate, showingparticularly the manner in which the bars are supported. Fig. 3 is aside view of one of the bars. Figs. 4, 5,and 6 are on an enlarged scale.Fig. 4 is a view of the grilling-burner preferably employed and some ofthe parts connected therewith. Fig. 5 shows a cross-section through thepreferred form of grilling apparatus, the grilling-plates being in anelevated or horizontal position for grilling. Fig. 6 is a similar viewshowing the grilling-plates depressed for boiling. Fig. 7 shows aleftside elevation of the hot-plate. Fig. S shows a vertical section onthe line 8 S of Fig. l looking in the direction of the arrows, some ofthe parts being omitted, and this gure also shows the upper part of thecooker. Fig. 9 is a perspective view of a drip-tray placed on the top ofthe oven below the hot-plate. Fig. lO is a view, on an enlarged scale,of a grilling-burner that may be employed, together with some of thedevices for supplying gas thereto. Fig. 11 shows a transverse section ofone form of grilling apparatus that may be used. Fig. l2 is a View, onan enlarged scale and in vertical section, showing the manner ofattaching the gas-cocks to the gas-bar. Fig. 13 is a plan view, withparts broken away, of one form of grilling-plate;

and Fig. 14: is a view of the gas-bar and some of its connections.

A A are brackets mounted over and at the opposite side edges of the ovenportion A2 of the gas-cooker and supporting an open rectangularhorizontal frame B, provided with burners B B2, tbc., which areremovably mounted in the frame. A countersunk ledge b around the inneredge of the frame B receives the removable bars b', which may be such asshown, or they may be of any suitable pattern, upon which the cookingutensils may rest. At the sides and front of the frame B areextension-bars b2, carried by rods b3, sliding in apertures in the frameB and in lugs b4 on the under face thereof. Since the outer edges of theframe B are curved in crosssection and are formed with recesses b5, theextension-bars h2 are preferably shaped to conform to such recesses, sothat when pushed in they will not detract from the appearance of theapparatus. Nhen drawn out, they enlarge the surface of the hot-plateavailable for the reception of utensils, as indicated.

The several burners Bl B2, &c., rest upon brackets C, projecting fromthe frame B, and at their outer ends they rest in apertures C C2, formedin the side brackets A A. These apertures are correspondingly formed inboth side brackets, and the frame B is provided with two points ofattachment c c' for each burner-bracket C to permit of all the burnersbeing reversed from the right to the left ide of the frame or stove.

The gas-bar D, which is a cored casting, has one end closed by aremovable cap d5, and the gas-supply pipe D is connected to the oppositeend of the casting. From each side of the gas-bar project two horizontalarms d, having at their ends upwardly-extending parts d. In each sidebracket are two L- shaped slots E. To attach the gas-bar to tho side,the parts dl are passed through the vertical parts of the slots E andthe bar D is then moved endwise to bring the parts d into the horizontalparts of the slots.

The gas-bar may be attached at either side of the hot-plate, all theburners being correspondingly reversed, as presently described, in orderto adapt the burner to the position in which the cooker' is mountedrelatively to the gas-supply connections. To permit of reversal of thegas-bars and also to afford access to the jets or nozzles supplying gasto the IOO open ends of the burners lying in the apertures C O2, hollowhubs fare formed on the top of the gas-bar, on the threaded tops ofwhich are seated the flanged ends of the gascocksf. A nut f2, screwingoneach hub, has an inwardly-projecting flange f3, that bears upon theflange of the gas-cock and clamps it in position against the face of thehub. From the -npper ends of the gas-cocks project laterally thegas-jets g, which discharge gas into the open ends of the burners. Thejets g may be cast in one piece with the cocks or they may be separatelyformed and attached. Should a jet become fouled by deposit from the gas,the nut f3 may be loosened, the cock turned around, and the jet cleaned.When the gas-bar is reversed or shifted to the opposite side of thestove, the several jets may be correspondingly reversed to adapt them totheir new position.

To provide for the gas connections to the oven-burners, the gas-bars maybe formed with two downwardly-extendin g connections D2 D3, Fig. 14, oneof which may be closed by a screw-cap d6, as shown, and the pipesupplying the oven burners connected with the other one. If there be butone of such connections, then when the gas-bar is at one side of thehot-plate the oven connections should be located near the front of thestove and when at the other side near the rear of the stove.

The annular burners B B3 have hollow supporting and gas and airsupplying bars or shanks curved at their outer ends for the purpose ofbringing the burners to their appropriate places in the frame orhot-plate. It is necessary or desirable to provide right and left handburners B B3. By the devices described the gas-bar may be placed oneither the right or left hand side of the stove to prospectively, havingappropriate nipples or apertures. For this burner there is an opengas-cock f', Figs. 10 and 12, having two plugs or valves f6 f7, so thatgas may be fed at will to both chambers of the burner or to either one,two jets g being provided, as indicated. Fig. 12 serves to illustratethe construction of the gas-cocks whether adapted to supply a burnerhaving one chamber or two. Grillplates H of ordinaryconstruction, one oneach side of the burner and in a plane between the two series ofapertures, are mounted at one end in one of the brackets C and at theother end in apertures 71, Fig. 13, in one of the sidev brackets, andthey also rest upon shoulders formed on the burner B4.

A tray I, having an enameled surface, preferably white, withupwardly-extending rear and side iianges anda downwardly-extending frontflange, fits between the side brackets A A and completely covers andprotects the top of the oven-casing, on which it rests.

I prefer to employ a grilling device of the construction shown in Figs.1, 4, 5, and 6. In this form of apparatus the grilling-plates K arepivoted near their outer edges to one of the brackets C and to one ofthe side brackets A A', and by means of the lever L, constructed andarranged in the manner shown or in any suitable manner, the plates maybe rocked to bring their inner edges above the nipples or apertures kfor grilling, as shown in Fig. 5, while for boiling the plates may bedepressed, as shown in Fig. 6, in which position the lateral jets offlame from the burners will pass across the upper surfaces of the platesand then upwardly by impinging against a vertical flange or rib 7d,extending lengthwise across the upper face of each plate, asindicated-in Fig. 6. The lever L is shown as consisting of a rock-shaftmounted in perforated lugs Z on one of the side brackets and having ahandle Z2 located near the front left-hand corner of the stove. Therock-shaft is provided with arms Z, which engage the inner ends of theplates K and support these plates in both their elevated and depressedpositions. In Figs. 5 and 6 I have shown the plates K cooperating with adouble burner similar to that shown i'n Fig. 11 and already described.In this case,however,l make the upper part M of the burner of smallerdimensions and supply it with a less quantity of mixed air and gas, thispart of the burner furnishing a slight flame for slow cooking orsimmering, and during its operation grilling may be done with the platesand lower part M of the burner, which is of considerably greatercapacity. Should an intense boilingflame be desired, the grillingplatesmay be depressed and both parts of the burner used in conjunction. Thetwo parts of the burner which are designated M M are really two separateburners and may be so considered. I have shown and described them asabove merelybecause to combine the two burners in one casting is aconvenient, suitable, and practicable way of making them, as the tworequire but one means of support in the hot-plate. The pivotedgrill-plates and their burner or burners as well as thegrill-plate-operating lever may be reversed when the gas-paris shifted.

I claim as my inventionl. A gas-cooker, comprising a hot-plate or openframe, the supporting side brackets having a corresponding series ofburner-apertures, burners detachably mounted in the frame, a reversiblegas-bar, means for detachably connecting it with either bracket, andreversible gas cocks and jets mounted on the gas-bar.

2. The combination with a gas-cooker, of a detachable gas-bar providedwith arms proj ecting laterally from opposite sides of it, and

IOO

IIO

a hot-plate having brackets on each side each of which is provided withapertures to receive said arms whereby the gas-bar may be Cietachabiyconnected with either side of the hot-plate.

3. The combination of the side brackets of the hot-plate, the gas-barhaving arms adapted to connect therewith either of said brackets,reversible gas cocks and jets mounted on the gasbar, the detachableburners receiving gas from the gas-j ets and devices for supporting saidburners so that they may project from either of said side brackets.

4. A gas-cooker comprising an oven-casing, a hot-plate mounted above itand comprising an open frame with vertical side brackets, burners in thehot-plate and a detachable enameled tray placed under the burners of thehot-plate between the vertical brackets, covering the top of theoven-casing and having upwardly-projecting flanges on three sides, and adoWnWardly-projecting flange at the front.

In testimony whereof I have hereunto subscribed my name.
